Description
Technical Field
The invention relates to the field of oil mist treatment, in particular to efficient electrostatic workshop oil mist treatment equipment and a working mode thereof.
Background
The working principle of electrostatic workshop oil mist treatment is that oil mist particles in mixed gas containing oil mist are charged, and the charged oil mist particles are adsorbed on a dust collecting polar plate under the combined action of electric field force, mechanical force, wind force and other acting forces, flow to an oil collecting area of an electrostatic device under the action of self gravity and are discharged through an oil discharge pipe.
In a nylon filament production workshop, the spinning production process requires that the filament bundles must be heated and drawn, and the heating and drawing of the filament bundles can cause the volatilization of an emulsified oil agent, so that oil mist is formed in the air, and the air is polluted. This is necessary to remove oil mist and purify the air in the workshop to ensure that the discharged air does not affect the health and natural environment of surrounding residents.
However, the electrostatic workshop oil mist treatment in the production process of the nylon filament at present has the following defects: the oil mist generated in the nylon filament workshop is not oil mist particles generated in the process of pure gold emulsified oil agent spraying and evaporating, fine thread ends generated in the process of production and winding of silk threads and dust existing in the workshop are also generated, the thread ends, the dust and the like enter an electrostatic field and collide with a discharge electrode and a dust collection polar plate, an electrostatic device is damaged, and excessive thread ends and the dust enter the electrostatic field to cause gas turbulence in the electrostatic field, so that the oil mist particles are not favorably captured by the dust collection plate.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide efficient electrostatic workshop oil mist treatment equipment and a working mode thereof, and solves the problems in workshop oil mist treatment.
The technical scheme is as follows: the invention provides efficient electrostatic workshop oil mist treatment equipment and a working mode thereof. Air in the nylon filament workshop is absorbed and collected through an oil mist suction device, is subjected to dust removal, oil mist particle removal, degradation and adsorption through a filtering dust removal device, an electrostatic oil removal device, a biochemical emulsification device and a spraying water washing device respectively, and then is discharged from an exhaust device after being purified. All the structures cooperate with each other to finish the high-efficiency oil mist treatment work.
The dust filtering and removing device is provided with a first filter screen, a second filter screen and a third filter screen, and the first filter screen, the second filter screen and the third filter screen are sequentially arranged inside the dust filtering and removing device. The dust discharging effect is improved by performing the dust discharging effect on the absorbed air for many times.
The filter mesh number of first filter screen, second filter screen and third filter screen increases in proper order, first filter screen is 100 meshes, the second filter screen is 300 meshes, the third filter screen is 500 meshes. Considering that the sizes of thread ends and dust particles in the air are different, the filter screen with the small aperture is directly selected to easily cause the phenomenon of filter screen blockage, so that the air circulation is not facilitated, and the low oil mist treatment capacity is realized.
The ratio of the distance between the discharge electrode and the dust collecting polar plate in the electrostatic oil removing device to the distance between the discharge electrodes is 0.6-0.7. The distance between the discharge electrode and the dust collection polar plate is increased, the corona voltage is increased, the pressure intensity of the electrostatic field is small, the tightening speed of the charged oil mist particles is reduced, the oil mist particles are not easy to capture, and the distance is too small, so that ignition spark is generated to damage an electrostatic device; the distance between the discharge electrodes is too wide, a dead zone exists, the electric field intensity is weakened, and the discharge intensity is reduced due to the shielding effect of the two homopolarity electrodes if the distance is too narrow. And when the distance ratio between the discharge electrode and the dust collecting polar plate and the distance between the discharge electrodes is set to be 0.6-0.7, the corona current density of an electric field is maximum, so that the oil mist removing efficiency of the electrostatic oil removing device is improved.
The discharge electrode in the electrostatic oil removal device is in a sawtooth shape. The adoption of the sawtooth-shaped discharge points can reduce the distance between the discharge electrode and the dust collecting polar plate, reduce the required working voltage, keep higher corona current density, reduce the secondary back-lifting and turbulent flow phenomena of oil mist particles and improve the oil mist purification efficiency.
The spraying and washing device comprises an air-equalizing plate structure, a spraying structure and a water baffle plate structure, wherein the air plate structure, the spraying structure and the water baffle plate structure are sequentially arranged along the flowing direction of air. The air degraded by the biochemical emulsifying device uniformly enters the spraying structure through the air equalizing plate structure to be sprayed and adsorbed, and then is dehumidified and dried through the water baffle structure. Thereby removing saturated fatty acids remaining in the air.
The spraying structure comprises a first spraying frame and a second spraying frame, and the first spraying frame and the second spraying frame are arranged in parallel. And the spraying is carried out for multiple times, so that the overall spraying strength is improved.
And the first spraying frame and the second spraying frame are arranged in a reverse spraying mode. The reverse spraying device is used for spraying air entering the spraying structure in an all-dimensional mode, and the overall spraying adsorption capacity is improved.
And the device is also provided with a sewage recovery device which is respectively connected with the electrostatic oil removal device, the biochemical emulsification device and the spraying washing device. Saturated fatty acid contained in the oil mist is dissolved in water through the treatment of the electrostatic oil removal device, the biochemical emulsification device and the spraying and washing device, and can be sent to a soap factory to be used as a production raw material through certain treatment, so that waste is changed into valuable.
A working method of efficient electrostatic workshop oil mist treatment equipment comprises the following specific steps:
1) air in the nylon filament production workshop is absorbed and collected through an oil mist suction device and enters a filtering and dust removing device;
2) carrying out step-by-step dust discharging work sequentially through a first filter screen, a second filter screen and a third filter screen;
3) the air after dust discharge enters an electrostatic oil removal device, oil mist particles flow to an oil collection area of an electrostatic device under the action of self gravity on a dust collection polar plate of an adsorption knife under the electrostatic action, and then are discharged through an oil discharge pipe and enter a sewage recovery device;
4) the air without most oil mist particles reaches a biochemical emulsifying device for further degradation, and sewage containing degraded substances enters a sewage recovery device;
5) under the action of the wind equalizing structure, the air enters the spraying structure position in the spraying and washing device in a relatively stable state, under the countercurrent injection of the first spraying frame and the second spraying frame, the substances such as particles, saturated fatty acid and the like contained in the air are further removed through the spraying and adsorbing action, and the sewage enters the sewage recovery device;
6) the sprayed air is dehumidified and dried through a water baffle structure;
7) the clean air after the purification treatment is discharged through an exhaust device.
The technical scheme shows that the invention has the following beneficial effects: 1) the dust removal treatment is carried out before the oil mist treatment is carried out on the air in the nylon filament production workshop, so that the interference of thread ends, dust and the like to an electrostatic field and the damage to an electrostatic device in the oil removing process are avoided, the oil mist removing capability is improved, and the loss is reduced; 2) the double-row reverse spraying frame is arranged at the spraying structure, so that the spraying range is improved, the spraying adsorption capacity is improved, and the cleanliness of the discharged air is improved; 3) the sewage generated in the treatment process is recycled, so that the energy consumption is reduced, and the environment is protected.
